The War of Curzola was fought between the Republic of Venice and the Republic of Genoa due to increasing hostile relations between the two Italian republics. Spurred largely by a need for action following the commercially devastating Fall of Acre, Genoa and Venice were both looking for ways to increase their dominance in the Eastern Mediterranean and Black Sea. Following the expiration of a truce between the republics, Genoese ships continually harassed Venetian merchants in the Aegean Sea.
